Answer:

63

Step-by-step explanation:

This is because 25% of 84 is 21. He knows how to play 21 songs. 84-21=63.

63 is how many songs he does NOT know how to play.

Answer:

The answer is 63.

----------------------------------

24% of 84 is 21. 84 - 21 = 63.

Answer:

B

Step-by-step explanation:

when rewriting it, it would be 2+5 because subtracting a negative number is the  same as adding.

so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)

Answer:

A. it would be Pete's gym because he doesn't have to pay for a membership as well as paying $30 per hour he only has to pay for the hourly cost.

B. Lars-starts at 20 then goes to 50 then 80 ect... goes up by 30 starting at 20 because of the membership he payed.

Pete's- starts at 0 then to 40, 80, 120, 160 ect... goes up by 40 starting at zero.

Answer:

15 times x which would be the students   or you could do 2550 divided by 15 and you get 170 students

Step-by-step explanation:

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

Answer:

Step-by-step explanation:

Answer:

4 wooden and 3 plastic

Step-by-step explanation:

4 (wooden) × 2 - 5 = 3 plastic

3 (plastic) + 4 (wooden) = 7 total

The number of plastic frames is 4 and the number of wooden frames is 3.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given statement:

The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.

The total number of frames sold by Tristan is 7.

Write the equation for the above statement,

p = 2w - 5

Here, p is a plastic frame and w is a wooden frame,

p + w = 7

Solve the equation by using the elimination method,

p = 4 and w = 3

Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

Answer:92.81

Step-by-step explanation:

Answer:

$82.27

Step-by-step explanation:

First, figure out how much it would be without tax.

(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25

Then, multiply this number by your tax rate.

77.25*6.5 = 5.02

Lastly, add your original total with this tax amount for your answer.

77.25+5.02= 82.27

Answer:

12 miles

Step-by-step explanation:

you would multiply 4/9 by 27 and you would get 12 miles in total.

Answer:

A)

[tex]\displaystyle \frac{1}{12}[/tex]

B)

[tex]\displaystyle \frac{3}{5}[/tex]

C)

[tex]\displaystyle \frac{17}{24}[/tex]

Step-by-step explanation:

Part A)

The Hendersons were traveling 1/3 of the distance on the first day.

However, they had to stop, having only traveled 1/4 of the 1/3 distance.

So, we can multiply the two fractions together.

Therefore, the fraction of the total distance they traveled is given by:

[tex]\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}[/tex]

The Hendersons traveled 1/12 of the total distance.

Part B)

We are assuming the bottle of milk was full at the beginning.

So, at the beginning, there were 1/1 bottle of milk left.

Howie fed a piglet 1/5 of the bottle. So, there is now:

[tex]\displaystyle 1-\frac{1}{5}[/tex]

Of the bottle left.

Making common denominators and subtracting yields:

[tex]\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]

So, after feeding the piglet, 4/5 of the bottle of milk was still there.

3/4 of the remainder was fed to a calf.

So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:

[tex]\displaystyle \frac{3}{4}\times\frac{4}{5}[/tex]

Multiply:

[tex]\displaystyle =\frac{12}{20}=\frac{3}{5}[/tex]

So, the calf drank 3/5 of the bottle of milk.

Part C)

Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.

First, convert 2 (5/6) to an improper fraction. So:

[tex]\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}[/tex]

Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:

[tex]\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}[/tex]

So, Nathan used 17/24 loaves of bread per sandwich.

Answer:

y = -7

Step-by-step explanation:

It's a horizontal line so y is constant, it would be y = b because the slope is 0.

Since it passes through the point (5, -7) we can assume the line is at y = -7
